To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
Updated review -- 3/31/2019: I only use this glue occasionally and it has served me well. However, today I discovered that most of the hardener has solidified within the past year. There was a little left so I could get my small gluing project done, but I now have over a half bottle of the product that I cannot use. The problem is even worse for the 15-minute version of this glue; all of the hardener has solidified. I used it even less often, so over 80% of it has gone to waste. Next time I will buy a smaller bottle of epoxy.
Original review -- 12/16/2012 The other reviews are correct about this glue drying quickly. It worked well for a suitcase repair I did where I had to hold together pieces of a plastic frame under tension while the glue set. I found that I could let the glue sit for about 2 minutes after mixing, then quickly apply it, hold the pieces together for another 6-7 minutes, relax my grip of bit, and then stop after 10 minutes total from mix time. It helped to have a timer in front me while I held the pieces together. If you get the glue on your fingers while you are holding the pieces, you should move them around a bit to prevent them from sticking fast. After I released my grip on the repaired object, I immediately cleaned my fingers with acetone and then soap and water -- glue removal was easy if attended to quickly.
Much better than epoxy in small tubes and infinitely better than those appalling double syringes which never seem to dispense equal volumes of epoxy and hardener. These bottles are a nice soft sqeezy plastic with good long colour coded nozzles and clip on caps. It's easy to dispense very small quantities by eye and for larger mixes there are clear graduations on each bottle. It sets quickly and gives a good strong bond. It's the only 5 minute epoxy I'll consider buying in future.
Two part epoxies are getting hard to find in two separate containers. This is the most economical way to do two-part glues. No tinker would be without the "compound-X" of fine sawdust folded into freshly mixed resin and catalyst hardener. The essence of fiberglass in exactly the right volumes that do not endanger the loss of components to sloppy use as with the regrettable double syringe systems currently being marketed.
Other than the putrid smell that is emitted when the product is combined, this epoxy is awesome. It definitely cures quick, maybe too quick, so make sure that you can set whatever you are putting together or repairing in a quick amount of time, otherwise, get another product.
I used the product for an unusual application--attaching bamboo slats to a mirror. The product worked quickly and is holding well. Moisture in the bathroom will challenge the holding power, but I expect it will work well.
